Throughout most of the twentieth century, electric propulsion was considered the technology of the future. Now, the future has arrived. This important new book explains the fundamentals of electric propulsion for spacecraft and describes in detail the physics and characteristics of the two major electric thrusters in use today, ion and Hall thrusters. The authors provide an introduction to plasma physics in order to allow readers to understand the models and derivations used in determining electric thruster performance. They then go on to present detailed explanations of: Thruster principles Ion thruster plasma generators and accelerator grids Hollow cathodes Hall thrusters Ion and Hall thruster plumes Flight ion and Hall thrusters Based largely on research and development performed at the Jet Propulsion Laboratory (JPL) and complemented with scores of tables, figures, homework problems, and references, Fundamentals of Electric Propulsion: Ion and Hall Thrusters is an indispensable textbook for advanced undergraduate and graduate students who are preparing to enter the aerospace industry. It also serves as an equally valuable resource for professional engineers already at work in the field.
Attitude Dynamics and Control of Space Debris During Ion Beam Transportation provides an overview of the cutting-edge research around the topic of contactless ion beam transportation for the removal of space debris. This practical guide covers topics such as space debris attitude motion, the motion of rigid materials in an inhomogeneous high-speed rarefied medium, gravity gradient torque, and more. The book examines and compares the various ways to control the spatial motion of space debris, such as engine thrust or altering the direction of the ion beam axis, and offers simple mathematical models for analyzing system behaviors. - Provides insight on the features, advantages, and disadvantages of contactless ion beam transportation of space debris - Demonstrates how classical mechanics, nonlinear and chaotic dynamics, and methods of stability theory are applied during the ion beam method - Includes simple mathematical models describing the behavior of the considered mechanical system, allowing the reader to understand the nature of the studied phenomenon
Over the last forty years, plasma supported processes have attracted ever - creasing interest, and now, all modern semiconductor devices undergo at least one plasma-involved processing step, starting from surface cleaning via coating to etching. In total, the range of the treated substrates covers some orders of magnitude: Trenches and linewidths of commercially available devices have - ready passed the boundary of 100 nm, decorative surface treatment will happen 2 in the mm range, and the upper limit is reached with surface protecting layers of windows which are coated with ?/4 layers against IR radiation. The rapid development of the semiconductor industry is inconceivable wi- outthegiantprogressintheplasmatechnology.Moore’slawisnotcarvedinto 1 stone, and not only the ITRS map is subject to change every ?ve years but also new branches develop and others mingle together. Moreover, the quality of conventional materials can be improved by plasma treatment:Cottonbecomesmorecrease-resistant,leathermoredurable,andthe shrinking of wool ?bers during the washing process can be signi?cantly reduced. To cut a long story short: More than 150 years after the discovery of the sputtering e?ect by Grove, plasma-based processes are about to spread out into new ?elds of research and application [1]—no wonder that the market for etching machines kept growing by an annual rate of 17 % up to the burst of the internet bubble, and it took only some years of recovery to continue the voyage [2].
This book presents best selected research papers presented at the Thirteenth International Conference on Applied Mathematics and Mechanics in the Aerospace Industry (AMMAI 2020), held from September 6 to September 13, 2020, at the Alushta Health and Educational Center (The Republic of Crimea). The book is dedicated to solving actual problems of applied mechanics using modern computer technology including smart paradigms. Physical and mathematical models, numerical methods, computational algorithms, and software complexes are discussed, which allow to carry out high-precision mathematical modeling in fluid, gas, and plasma mechanics, in general mechanics, deformable solid mechanics, in strength, destruction and safety of structures, etc. Technologies and software systems that provide effective solutions to the problems at various multi-scale levels are considered. Special attention is paid to the training of highly qualified specialists for the aviation and space industry. The book is recommended for specialists in the field of applied mathematics and mechanics, mathematical modeling, information technologies, and developers of modern applied software systems.
